Question

.what is moment of inertia of Uniform disc​

Answer 1

Answer:

Moment of inertia of the disk about an axis passing through the center and perpendicular to the plane of the disc is given by 21MR2. ... So, distance between the axes = radius of the disk. Thus, by parallel axes theorem, we have 21MR2+MR2=23MR2

Answer 2

Moment of inertia of the disk about an axis passing through the center and perpendicular to the plane of the disc is

given by 1/2MR2

Now, we have to find the moment of inertia about a parallel axis, but passing through the edge of the disk. So, distance between the axes = radius of the disk.

Thus, by parallel axes theorem, we have

1/2MR2+ MR2 = 3/2 MR2
